What Sleep Is and Why All Kids Need It - 0 views

  • The average kid has a busy day. There's school, taking care of your pets, running around with friends, going to sports practice or other activities, and doing your homework. By the end of the day, your body needs a break. Sleep allows your body to rest for the next day. Everything that's alive needs sleep to survive. Even your dog or cat curls up for naps. Animals sleep for the same reason you do — to give your body a tiny vacation.

Why do we get sick? - HowStuffWorks - 2 views

  • As an example, think of a person who has a cold. That person may cough into his or her hand and then touch a doorknob, thus placing the cold virus on that doorknob. The virus may die on the doorknob, but it's also possible that the next person to touch the doorknob will pick it up. If that person then touches food with the unwashed hand and consumes the food, the virus is now inside the body.
  • The earliest physicians thought that illness and disease were a sign of God's anger or the work of evil spirits. Hippocrates and Galen advanced the concept of humorism, a theory which held that we get sick from imbalances of the four basic substances within the human body, which they identified as blood, phlegm, black bile and yellow bile. Paracelsus, a Renaissance-era physician, was one of the first to posit that sickness comes from outside sources, rather than from within.Today, we know that there are two major kinds of diseases: infectious and non-infectious.
    • Regina Cantu
       
      For example, if a person has gotten a cold and sneezes into their hand, then suddenly they touch the light switch, They leave the cold there, it may also be that the cold virus dies there, but it may also be that the next person who touches the light switch gets it in their hands. If they go to eat, and they don't wash their hands and they touch what they are going to eat they get it in their mouth and now they have the cold.

Why do certain animals only live in certain parts of the world? - 1 views

  • you cannot derive a polar bear of its cold climate because they are animals who have adapted to their surroundings. Their fur is a significant trait that enables them to survive the winter climate, & if they are placed in a desert for example, they will die from the heat & the inability to adapt to the weather.
    • morales5853
       
      Animals have their own way to be because it will help them survive where they live, for example, a scorpion wont be born with lots of fur, because he lives in the desert, were there's lots of heat.
    • morales5853
       
      A animal is born the way he can survive in its habitat, because if a animal that lives in the north pole has only skin and not fur he may probably die because of the coldnes the day he is born

Clocks - How Time Works - 1 views

  • A day consists of two 12-hour periods, for a total of 24 hours. An hour consists of 60 minutes. A minute consists of 60 seconds. Seconds are subdivided on a decimal system into things like "hundredths of a second" or "millionths of a second."
    • marino5856
       
      There is 24 hours in a day because  they first divided 60 and that equals 12. So 12 plus 12 equals 24 so thats how they had 24 hours in a day.
  • hat's a pretty bizarre way to divide a day up. We divide it in half, then divide the halves by twelfths, then divide the twelfths into sixtieths, then divide by 60 again, and then convert to a decimal system for the smallest increments. It's no wonder children have trouble learning how to tell time.
  • How long is a day? It's the amount of time it takes for the Earth to rotate one time on its axis. But how long does it take the Earth to rotate? That is where things become completely arbitrary. The world has decided to standardize on the following increments:

  • Why are there 24 hours in a day? No one really knows. However, the tradition goes back a long way. Take, for example, this quote from Encyclopedia Britannica:
  • Why are there 60 minutes in an hour and 60 seconds in a minute? Again, it is unclear. It is known, however, that Egyptians once used a calendar that had 12 30-day months, giving them 360 days. This is believed to be the reason why we now divide circles into 360 degrees. Dividing 360 by 6 gives you 60, and 60 is also a base number in the Babylonian math system.
    • marino5856
       
      The Egyptians had a calendar that has 12 months so that equals 360 day in total. Also science they new that there is 360 days in a year thats why a circle is 360 degrees. The Roman people invented that so that in the clock there is not 24 hours in a clock so there is 12 am and 12pm.
  • What do a.m. and p.m. mean? These abbreviations stand for ante meridiem, before midday, and post meridiem, after midday, and they are a Roman invention. According to Daniel Boorstin in his book The Discoverers, this simple division of the day into two parts was the Romans' first increment of time within a day:

Why is the sky blue, sunsets red, and clouds white? * KidExplorers * ChristianAnswers.Net - 0 views

  • The sky is blue because of the “scattering” of sunlight. The color blue has a shorter wavelength and greater energy than the other colors. As a result, blue is selectively absorbed by air molecules, then given off again in all directions. The other colors are less scattered, and therefore not usually seen.
    • guzman5860
       
      The sky is blue because its wavelength is shorter and it has more energy than other colors and the other colors are not always seen.
